The seismic network recorded three rockfalls and two volcano-tectonic earthquakes this week.

Measurements of the SO2 flux were taken from the helicopter on 26 October and 1 November. There were four traverses on 26 October and eight on 1 November, with average fluxes of 212 and 142 tonnes per day respectively.

Pyroclastic flows can occur at any time without warning on any side of the volcano, including Gages from where they can travel rapidly into Plymouth. Tracks across the Belham Valley can be destroyed or heavily modified by flash flooding or lahars, and caution should be exercised crossing the valley during and after rainfall.

The Hazard Level is 1. There is no public access to Zone V, including Plymouth. Maritime Zones E and W are daytime transit only between sunrise and sunset (boats may sail through the zone but must not stop). Anyone who ignores these restrictions is liable to be prosecuted.
